Don't try to cultivate immortality; mortals live longer than immortals.

"This... is actually a bit difficult to explain!"

Jiang Yaoguang hesitated for a moment, then took out a small, round object from her pocket and gently pressed the button on top. Instantly, a semi-transparent virtual file came into view.

The words "Cross-border Trial, Registration Instructions" on the screen were particularly eye-catching.

Duan Xuan glanced at the document and quickly read through it, a look of surprise on his face.

Well... how should I put it?

Since the fall of Lin Tianzun, Guixu and its associated smaller worlds have faced deep-seated malice.

Cultivators from countless realms have tried to invade this place. If it weren't for the protection of the "Qiankun Hunyuan Protective Array" left behind by the Heavenly Venerable, Guixu would probably have fallen long ago.

However, it wouldn't be accurate to say that Guixu was completely at a disadvantage.

On the contrary, Guixu has been fighting back all along.

Moreover, there are countless contingency plans prepared from multiple dimensions.

The most important thing is naturally the implementation and enforcement of the "Obligatory Immortal Cultivation Method," which aims to cultivate a new Celestial Venerable to protect the Ruins of Return.

Besides these, there are many other ways.

It can be said to cover multiple fields and include all the realms of cultivators from Qi Refining to Mahayana.

This cross-disciplinary trial registration is one of them.

As the name suggests, this trial is based on voluntary participation and uses a group-based system. The minimum requirement is late-stage Qi Refining and a minimum of three players. Once a group is successfully formed, a small instance from an interface opposite to Guixu will be randomly selected as the trial venue.

Duan Xuan was a little confused.

Looking up at Fairy Yaoguang, he said, "Jiang, three mere late-stage Qi Refining cultivators are heading alone to the enemy's realm. Isn't that just courting death?"

"Don't worry!" Jiang Yaoguang appeared very calm: "Since it's a trial, there will naturally be some risks, but it has nothing to do with courting death."

"On the contrary, the specific locations were carefully selected and evaluated by the Immortal Alliance. They are actually very safe and are purely used for grinding monsters and gaining experience. In addition, you can also get contribution points."

"Contribution points?"

"Yeah, this is much more useful than spirit coins, do you want to go?"

"Well... let me think about it. I'll get back to you tomorrow."

Jiang Yaoguang nodded.

Such an important matter shouldn't be decided on the spot, and the other party's actions are consistent with his composed personality.

"Okay, then I'll wait for your good news tomorrow."

The two then added each other as friends on "Xianxin," said goodnight to each other, and then parted ways.

……

Back in his dorm, Duan Xuan closed the door and then eagerly activated the system.

With a slight buzzing sound, a waterfall of data suddenly appeared before my eyes, piling up into a petite, adorably dressed young girl.

The girl was beautiful, with a ponytail and binary "0" and "1" floating on the ends of her hair.

The security system for Duan Xuan's dormitory had long been taken over by Ling Yun, and now that there was no third person around, she could act with impunity when she appeared.

"System, is what Jiang Yaoguang said true? How safe is this kind of experiment? Are there detailed statistics on the casualty rate of the cultivators who participated in the trial?"

From Duan Xuan's perspective, he didn't really intend to take any risks. As the owner of a true Heavenly Spiritual Root, why would he be foolish enough to wade into troubled waters?

Since I have such extraordinary talent, why shouldn't I stay put a little longer?

Going to other interfaces without leaving the starting village seems incredibly foolish.

It would be safer to cultivate to the Mahayana stage before going out to have fun!

That's true, but Duan Xuan still hoped the system could provide a rough assessment.

Regardless, even if it was out of curiosity, he was still very interested in the trial that Jiang Yaoguang had mentioned.

After all, the term "other interfaces" itself is full of magic.

Although Duan Xuan had long known that besides Guixu, there were many other parallel cultivation worlds in this universe, he was naturally completely unaware of their specifics given his current cultivation level.

Now that such an opportunity has suddenly presented itself, how could he not be curious?

Therefore, Duan Xuan and Ling Yun had an in-depth and detailed exchange on this issue.

……

Early the next morning.

After Duan Xuan got up, he was still brushing his teeth in the bathroom when his phone screen lit up with a new message.

Duan Xuan returned to the living room, picked up his phone, and opened Xianxin. He saw that Jiang Yao had sent him a smiley face emoji: "Duan Xuan, what's your decision?"

"this……"

Duan Xuan hesitated for a moment, then, recalling the conclusion he had reached with Ling Yun, typed in the chat box: "Okay, I agree. But as you said, the minimum requirement for this trial is a team of three. So, has the other member, Jiang, been decided?"

"I have someone in mind, and you're actually quite familiar with them."

Jiang Yaoguang replied very quickly: "It's your friend Zhou Ran, and he's in the same class as us. As the owner of the silly spiritual root, even if he hasn't cultivated to the late stage of Qi Refining, he shouldn't be far off. We can give him three days."

"If he can break through, we'll bring him along to join the group purchase. We can share the benefits. If not, we might as well look for other candidates."

"Hmm, not bad."

Duan Xuan was very satisfied with Jiang Yaoguang's answer.

Coincidentally, he also wanted to bring his brother along so that the two could look after each other.

"In that case, send me a copy of the registration agreement for the interdimensional trial, and I'll contact that kid Zhou Ran."

"Can."

Jiang Yaoguang replied.

Less than two minutes later, Duan Xuan received a new file. He opened it with the built-in plugin of Xianxin and found it to be the electronic version of the registration agreement.

"Ranzi, are you there? Are you there? You're not dead, reply to my message quickly."

Duan Xuan sent a mischievous smiley face.

At that moment, Zhou Ran had just gotten up and was taking a dump while scrolling through short videos when she suddenly received a message from Duan Xuan.

Completely bewildered: "What's going on? Why all the mystery so early in the morning? It's disturbing my pooping."

Duan Xuan was speechless.

This is the aftereffect of being too close to your best friend. You don't know what they're saying, and even if you try to be subtle, they're always so blunt. Luckily, I haven't eaten breakfast yet.

Without saying a word, Duan Xuan sent over the registration agreement for the cross-world trial.

I was about to explain myself when I received a message from the other party: "First came a string of surprised emojis."

"Damn, that's so cool! Where did you find this news? You're such a good son, always thinking of your father when there's good news."

"Get out of here! I think you're out of your mind. You can't even figure out who the son and father are, the basic father-son relationship."

After a typical, pointless chatter between close friends, the two finally got to the point.

"So, are you going or not?"
